UTV-SBI-19L includes:
- The ONLY 100% UTV designed Battery Isolator available w/PEP Lithium
- At least one of your batteries should be Lithium
- Industry’s simplest installation
- Brand: True® Amalgamated
- Manufacturer Part Number: UTV-SBI-19L
Built for Lithium. Proven in the Field. Trusted by UTV Owners.
The UTV-SBI-19L was developed primarily to work with the latest lithium batteries that have a voltage of 13+ volts and stator-style charging devices. You must have at least one lithium battery to allow the use of the product’s special PEP.
Lithium batteries are a distinct kind of battery with sophisticated characteristics that need special management programming to preserve. The lithium batteries that are accessible for this business are 13+ volt batteries, not 12-volt batteries; thus, the True isolator is configured to handle this and other characteristics that might not be as evident. We are happy to present the recently released lithium battery isolator designed specifically for UTVs after taking the time to do the necessary studies and testing.
The only completely adhesive-sealed, 100% waterproof cables in the market are included with every True® lithium battery isolator. There are two mounting options for this isolator. Use a 3M Dual Lock fastener or hang it from cables. Outstanding performance and quality from True Amalgamated.
As of right now, no alternative battery isolators made specifically for lithium batteries are available on the market.
Frequently Asked Questions
1. What makes this isolator different from standard ones?
It’s specifically programmed for LiFePO₄ lithium batteries, which operate at higher voltages (13.2V–13.5V). Standard isolators often fail to engage or disengage properly with lithium systems, risking accessory drain or undercharging.
2. What is P.E.P. technology?
Power Efficiency Programming (PEP) maximizes charging efficiency from stator-based systems commonly found in UTVs. It ensures both batteries receive optimal charge without overloading the system.
3. How does the isolator know when to connect or disconnect?
It uses voltage-sensitive logic:
- Engages at 13.5V to connect both batteries for charging
- Disengages below 13.2V to protect the starter battery
There’s a built-in 10-second delay to prevent false triggers.
4. Can I monitor battery status?
Yes. The kit includes a dual-display waterproof voltmeter and a blue LED indicator on the isolator itself, which lights up when the batteries are connected and charging.
5. Is it compatible with other battery types?
While optimized for lithium, it also works with AGM and lead-acid batteries, making it versatile for mixed setups.
6. How easy is installation?
Very easy. The kit includes:
- Pre-cut, adhesive-sealed waterproof cables
- 3M Dual Lock™ fasteners
- Simple 3-wire connection—no ignition tapping required
It’s designed for plug-and-play use in UTVs like Honda Pioneer, Polaris RZR, and Can-Am.
7. Will it protect against electrical surges?
Yes. The isolator includes ignition surge protection, shielding your system from voltage spikes during startup or accessory use.

Needed for Lithium battery in Honda Pioneer 1000
I was using the previous model with my dual battery setup in my Honda. I decided to go with Lithium dual battery kit which required this update. Previous model still work well after 6 years.

Fantastic product, and this business takes phone calls.

Simple to set up. Functions as it ought to, or as I would have anticipated. With the help of my dual voltage meter, I can keep an eye on both of my UTV’s batteries and make sure the isolator is operating. is still operating well after being placed for more than a month.
